The 65RP hull was specifically designed to offer outstanding efficiency throughout the speed range. Her acceleration curve shows no dips, flat spots or other anomalies. Small but important characteristics - a main chine that never crosses the waterline, a lower chine that effectively provides lift, propeller tunnels with a finely-tuned geometry - all add up to produce a vessel that cruises with fuel economy at an 18-knots clip as well at slower displacement speeds.
